* Qualcomm Technologies, Inc. MSM ISPIF

Required properties:
- cell-index: ispif hardware core index
- compatible :
    - "qcom,ispif"
    - "qcom,ispif-v3.0"
- reg : offset and length of the register set for the device
    for the ispif operating in compatible mode.
- reg-names : should specify relevant names to each reg property defined.
- interrupts : should contain the ispif interrupt.
- interrupt-names : should specify relevant names to each interrupts
  property defined.
- camss-vdd-supply: phandle to GDSC regulator.
- mmagic-vdd-supply: phandle to mmagic regulator.
- vfe0-vdd-supply: phandle to vfe0 regulator.
- vfe1-vdd-supply: phandle to vfe1 regulator.
- clocks: list of phandles to the clock controller device and coresponding
  clock names.
- clock-names: name of the clocks required for the device used by the consumer.
- qcom,clock-rates: clock rate in Hz.
- qcom,clock-control: The valid fields are "NO_SET_RATE", "INIT_RATE" and
  "SET_RATE". "NO_SET_RATE" the corresponding clock is enabled without setting
  the rate assuming some other driver has already set it to appropriate rate.
  "INIT_RATE" clock rate is not queried assuming some other driver has set
  the clock rate and ispif will set the the clock to this rate.
  "SET_RATE" clock is enabled and the rate is set to the value specified
  in the property qcom,clock-rates.

Optional properties:
- qcom,num-isps: The number of ISPs the ISPIF module is connected to. If not set
  the default value used is 1
